Outline of Final Research Achievements |
Forest ecosystems have large and complex contribution to the carbon balance of biosphere. For global change forecasting due to the climate change, it is needed to get a deeper understanding of the system for more mechanistic modeling of carbon acquisition and partitioning within trees and within the different ecosystem pools. 13CO2 pules labelling was used to estimate the velocity and the residence time of carbon in the tree. Pinus densiflora, Quercus crispula, Quercus serrata, Lithocarpus edulis were used as model species. The velocity of carbon in Pinus densiflora was slower than other broad leave species, showing large difference on the residence time in trunk respiration across seasons. Especially, residence time in the winter was long. Most of the carbon fixed by the leaves of Quercus serrata flowed to the stem within 4 days. However a fraction of 13C fixed by the foliage remained in the leaves after long time suggesting that there are fast and slow residence time carbon pools.
